According to AI, there is good and bad news about finding the third 1982-D Small Date bronze cent–perhaps the most sought after coin due to social media hype about its lottery-prize-like value.
As you read this, remember that AI is not an expert numismatist. Maybe those folks would have used different metrics. But I am an AI authority as one of the top technology professors with 48 years at top research institutions. So I expect those fellow hobbyists will be commenting and demurring and otherwise questioning these results.
Let’s have some fun.
Only two of these transitional varieties have been found since it was theorized that a copper planchet with a small date might have left the Denver Mint. Here they are, authenticated.

Some more facts: There are seven common varieties of 1982 cents: The copper ones should weigh 3.1 grams; the zinc ones, 2.5 grams. The copper ones are Large Date, Philadelphia; Small Date, Philadelphia; and Large Date, Denver. The zinc ones are Philadelphia, Large Date; Philadelphia, Small Date; Denver, Large Date; and Denver, Small Date.
The coveted transitional variety weighing 3.1 grams has these markers:

AI factored these odds: a hobbyist looking for the third example every day in a dollar’s worth of Lincoln cent pocket change over 40 years as roughly 1 in 300,000,000, or a probability of 0.0000000033.
Let’s illustrate those odds. Imagine one 1982-D Small Date 3.1 grams is mixed into 300,000,000 total cents. Let’s stack those coins one atop the other. They would reach 283 miles high, surpassing the International Space Station. Blindfolded, you pick exactly one coin from that stack anywhere up the cosmic ladder.

What? You don’t like that analogy?
How about this: You are 20,000 times more likely to be hit by lighting than finding the third example.

Here’s the AI screenshot:

But there is good news, too. AI factors that odds of another example (as many as 15-50 might exist!) being circulated in pocket change are nearly 100% probability!
Here’s the screenshot:

It was gratifying to know that AI cited Proxiblog about coins coming from two working dies. You can read that article by clicking here.
AI also included these factors:
- The discovery coin was found in 2016.
- The second was found in 2019.
- This yields an empirical discovery rate of roughly 0.05 coins per year since the hunt began. This low yield confirms that while more coins exist, the vast majority of the 6.01 billion Denver cents have either been melted down, lost in landfills, or remain sitting unexamined in hoarders’ casual coin jars.
Summary of Your Search Odds
| Metric | Statistical Value |
|---|---|
| Odds a 3rd coin exists | ~100% (Virtually guaranteed) |
| Estimated total supply remaining | 15 to 50 coins |
| Odds per individual unsearched 1982-D cent | 1 in 300,000,000 |
Before you start celebrating and searching your grandparents’ coin jars, don’t count on winning the numismatic lottery. You would have better odds winning the Powerball jackpot (again hypothetically) if you bought a ticket every day for 40 years,
AI puts those odds as 1 in 20,000.
Remember the odds of the third 1982-D Small Date bronze coin? That’s 1 in 300,000,000!
Here is its breakdown of the math:
- Single Ticket Odds: The odds of winning the Powerball jackpot with a single $2 ticket are 1 in 292,201,338.
- Total Tickets Bought: Buying one ticket every day for 40 years (including leap years) equals 14,610 tickets.
- Cumulative Probability: Each ticket is an independent event. Your cumulative chance of hitting the jackpot at least once over those 14,610 tries is roughly \(0.005\%\) (or about 1 in 20,000).
Have you made the correlation yet?
Go to the corner gas station. Buy a Powerball ticket. Your odds of winning the lottery jackpot with that single ticket is roughly the same as finding the third 1982-D Small Date bronze cent after 40 years of searching for the unicorn!

If you are intent on searching for those theorized 15-50 examples of the 1982-D Small Date bronze cent, keep doing it. Miracles happen.
Your own existence is 1 in 300,000,000!
AI states: “Yes, events with odds of 1 in 300,000,000 happen around us all the time. When dealing with massive populations or billions of trials, things that are nearly impossible for an individual become statistical guarantees on a larger scale.”
Let’s start with your own existence.
AI states, “Every person alive is the result of a 1-in-300-million event. During human conception, a typical fertile ejaculation releases between 100 million and 300 million sperm cells. The fact that one highly specific sperm successfully fertilized a specific egg to create your exact DNA blueprint means that your existence is equal to finding the third 1982-D Small Date bronze cent!”
